         SEMTECH UPDATES OUTLOOK; ANNOUNCES $50 MILLION STOCK BUYBACK

                  Outlook for Improved Gross Margin Unchanged

           Board of Directors Authorizes a $50 Million Stock Buyback

                                                       1:30 p.m. PST
                                                       Thursday, January 4, 2001

NEWBURY PARK, CALIFORNIA, January 4, 2001 - SEMTECH CORPORATION (Nasdaq: SMTC)
today announced that it expects to achieve analysts' consensus earnings
estimates of 23 cents per share for the fourth quarter ending January 28, 2001.
Semtech is forecasting that fourth quarter revenue will be sequentially flat
compared with third quarter levels.  Previously, the Company's sequential
revenue growth forecast was 7 to 9 percent for the fourth quarter.  For all of
fiscal year 2001, revenue is now forecasted to grow 47 percent and net income is
expected to increase over 100 percent compared to the prior year.

     Jack Poe, Chairman and Chief Executive Officer, commented, "Our backlog as
of the beginning of the quarter positioned the Company to meet our initial
revenue forecast, assuming normal historical turns were achieved.  Since that
time, OEM customers, contract manufacturers and distributors have adjusted their
ordering patterns to reduce inventory levels.  This combined with a temporary
slowdown in demand for certain communication equipment and personal computers,
will reduce our sequential revenue growth.   We expect the inventory correction
will be completed during the first quarter.  Revenue for the first quarter is
expected to be approximately flat compared with fourth quarter levels.
Sequential revenue growth should resume in the second quarter of fiscal year
2002."

     Mr. Poe added, "Gross margin continues to expand.  Introduction of new,
proprietary products out of our advanced communications, human interface devices
(HID) and ECL clock and logic product lines are being well received.  We are
also starting to see the benefit of focusing our power management business unit
on portable and telecommunication applications.  Based on the stream of new
products across all product lines and design wins from customers, we remain very
confident about the long-term growth of the Company."


Current Quarter Outlook

 .    Revenue for the fourth quarter ending January 28, 2001 is forecasted to be
     flat with the third quarter.

 .    Gross margin for the fourth quarter is forecasted to increase approximately
     110 basis points as compared to the third quarter.

 .    Operating expenses for the fourth quarter are expected to increase
     approximately $200,000 as compared to the third quarter.

 .    Interest and other income is forecasted at approximately $3.0 million for
     the fourth quarter.

 .    Diluted shares are forecasted at approximately 76.7 million for the fourth
     quarter, prior to giving effect to any stock repurchases.

Next Fiscal Year Outlook

 .    For fiscal year 2002, which ends January 27, 2002, the Company expects
     revenue growth of 25 to 30 percent and net income growth of 35 to 40
     percent over fiscal 2001.

 .    The Company expects to achieve its intermediate goal of 60 percent gross
     margins by the third quarter of fiscal year 2002, consistent with our
     previous forecasts.

     The Company expects to release fourth quarter and fiscal year 2001 results
on February 22, 2001.
